Furthermore, the circulation of air which is drawn in at considerable velocity around the plugs, has as beneficial effect in keeping the plugs cool.

This invention has been illustrated and described in connection with a straight eight motor, but it will be understood that the number and arrangement of the cylinders as well as the-carburetors, may be varied as del sired without changing the scope of the invention.

It will thus be seen that I have provided a novel air charging and distributing'construction which is decidedly simple and compactin construction and arrangement, and which may be particularly utilized. in connec-tion with motors. having afplurality of carburetorsfor efiieiently collecting and conducting purified air to the carburetors.
